Founded in 1989, the Icehotel in Swedish Lapland is built from the snow up each year, using ice from the local river. The rooms are designed by international artists and this year feature spacemen and an ice queen. The hotel has 35 suites, featuring ice carvings designed by 36 different artists from 17 countries. This room, King Kong, was created by Lkhagvadorj Dorjsuren. (Photo by Asaf Kliger/IceHotel/The Guardian)

A total of 30,000 cubic metres of snow and ice were used to construct the hotel, while the artwork was cut from 500 tons of crystal clear natural ice. This suite, Follow the White Rabbit, was created by artists AnnaSofia Mååg and Niklas Byman. (Photo by Asaf Kliger/IceHotel/The Guardian)

The Icehotel reopens each year in a new form. In this room, Ground Rules, created by Carl Wellander and Ulrika Tallving, icy snails take centre stage. (Photo by Asaf Kliger/IceHotel/The Guardian)
